sylvania, have invented certain new and use- `ful Improvements in Machines for Manufacturing Envelope, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a machine for manufacturing envelops, and more particularly large envelops, ,wrappersI or inclosures for magazines and other litelature adapted to be sent by mai-l or express.

The primary object of my invention is to rovide a machine of the above type where- 1n positive and reliable means are employed, as hereinafter set forth, for expeditiously and economically manufacturing envelops and wrappers. I Another object of this invention is to pro-` 'vide a machine of the above type wherein simple and effective means are resorted to for wrapping and sealing magazines or other matters placed in position in the ma* chine.

A further object of this invention is vto provide va continuously and automatically operated machine of the above type for wrapping and inclosing various kinds of. matter, parts of the machine being successively operated for folding a wrapper, sealing the saine Aand discharging the wrapped article from the machine.

A still further object of this invention is to provide a strong and durable wrapping machine that can be advantageously used by large publishing houses, the machine accomplishiiig automatically what has beenhereto liereiin'ifter specifically described and then' claimed.

Reference will now be had to thc drawings, wherein like numerals denote corresponding parts throughout the several views, in which:-

Figure 1 is a plan of the machine. Fig.

' 2 is a longitudinal sectional view of a portion of the machine.- Fig. 3 is a similar view illustrating the moistening device in action. Fig. 4 is a side elevation of a portion of the machine showing an article in the machine in position to be wrapped. Fig. 5 is a similar view illustratin the article as partially wrapped, also showing 'an ejector. Fig. 6 is a similar view showing the article completely wrapped, and Fig. 7 is a plan of a movable platform forming part of the machine, showing an article partially wrapped.

In describing my invention by aid of the drawings above referred to, I desire to point out that I intend said views as merely illustrative of an example whereby my invention may be applied in practice, and I do not limit my claims to the precise arrangements or constructions of the parts indicated. The

following description is therefore 'to .be (Jon` strued broadly, as including substitute arrangement and construction which are the obvious, equivalent of those shown.

The drawings show a platform 1 that is rectangular in plan, said platform being supported by uprights 2 and 3. The up* rights 3 are provided with bearings 4.foi a roll of paper 5. The paper from the roll 5 is adapted to pass between the uprights 8" and 2, beneath the platform 1, said paper passing between sets of transverse rolls 6 and 7 that are revolubly supported by hangers-8 arranged at the longitudinal side edges of the platform l. The paper also passes over stationary platforms i) and a movable platform 10. The stationary platforms 9 are supported 'by hangers 11, carried by the platform l. The movable plattform 10 is carried by a plunger 12 and said plunger can be raised and lowered by a hydraulic,

hand, treadle, or any other suitable means (not shown). The forward end of the platform 1 is provided with bearings 13 fora driven shaft 14 vthat can be operated by a motor or from any suitable source of power.` p

The driven shaft 14, adjacent to the bearings 125, is provided with beveled gear wheels` l5 meshing with beveled gear wheels 16 mounted upon the forward ends of longitudinal double spiral feed screws 17 that are revolubly supported in bearings 18, carried by the platform 1, at the forward and rear ends thereof. The feed screws 17 are adapted to shift blocks 19 back and foi-th beneath the platform 1 and said blocks are connected together by a transverse rodQD that has the ends thereof protruding beyond said blocks.

Slidably and rotatably mounted upon the ends of the rod 20 are grooved guide wheels v ing the cuttiiig action of the knife.

knife can be automatically operated by any suitable means. The platform l is provided with a transverse slot 31, adjacent. to the forward end thereof, and with longitudinal "21 engage depending by the platform 1, said 2 1 having integral cutter wheels 22. The cutter wheels 22 engage the paper as it passes over the platforms 9 and 10, said cutter wheelsV cutting the longitudinal edges of the paper and producing end flaps, as will hereinafter appear. The grooved guide wheels guide rails 23 carried guide rails determining the shape of the end flaps to be cut at the side edges of the paper. In order that the paper can be fed over the platforms 9 and 10the rolls 6 and 7 have the shafts 24 thereof provided with sprocket wheels and passing over said sprocket wheels is an endless sprocket chain 26 that causes said rolls to revolve in `1nison. One of the shafts 24 of the rearmost set of rolls 7 is provided with belt wheels 7, whereby the sets of rolls can be driven.

Located adjacent to the set of rolls 6 is a reciprocatory knife 28 that engages the underside of the paper and cuts the paper into desired lengths.' Above the knife .28 there isloca'ted'a transverse bar 2S) carried by hangers 30 connected to. the platform l.. The paper passes between the knife and the 'bar 29 and said bar supports the paper lpriis flap slots 32. The slots 32 are arranged adjacent to the guide rails 23 and conform in` normal position, the shafts 2li are placed in plan to the shape of said rails.

Movable above the platform l. is a T shaped head 33 carried by a plunger 34: that can be operated similar to paste applying devices 35 land 36 adapted to be moved through the slots The paste applying devices and 36 are in the form of reservoirs adapted to contain a 'paste paper through the medium of brushes 37,`

or mucilage which is applied` to the carried by the lower edges of the devices 35 and 36. The devices 35 and 36have lilling openings that are normally closed yby` driven shaft 14. The, supply of air to the hydraulic cylinders ll() is automatically controlled by valves 47 having the valve stems the plunger 1 2. The ends of the head 33 are provided with 3l. and 32 and are utilized for applying paste to the flapl pump 43, carried by one ofV thereof tripped byextensions 43, carried by a longitudinal rod 49 connected to a roller bearing 50. The roller bearing 50 has a revoluble wrapping roller 51 and said bearing is carried by the outer end of the piston rod 52. Besides the wrapping rollers shown in Figs. il and 5, there are two side rollers 53 thaty are shown in Fig. 7, said rollers being operated similar to the rollers The uprights 3 support another hydraulic cylinder 54; below the cylinderl 40, the' cy inder 54 being equipped similar to the cylinder 4l() and constituting an ejector. When the platform l0 is suiliciently lowered, the cylinder 54 can be placed in operation to eject the wrapped and sealed article from the platform.

The machine herein described. is adapted to be continuously operated and the knife 28 and the cutter wheels 22 sever the paper as it passes from the roll 5 over the platforms E) and l0.

The operation of the driven shaft lil can be reversed. whereby the cutter wheels will be moved back and forth, and any suitable mechanism can be ei'nployed for controlling the movement of the shafts la; and 24:. During the movement of the cutter wheels 2") the paper is held stationary upon the platform l0 `and while being held,

the devices 35 and 3G can be lowered to apply adhesive to theedges of the paper. .lifter the paste applyingdevices and the cutter wheels have been restored lo their operation and the platform ,l0 lowered. The severed end of the piece of paper is moved to the first set of rolls 7 and then there is a cessationin the operation of the shafts 2l until the platform is restored to its normal posit-ion. As the platform 1G is lowered, the magazine or article to' he wrapped is placed upon the cut piece of paper, andthe paper is therefore weighted down on the platform l() and the ends of the piece of paper drawn through the set. of 'rolls 7, as best shown in Fig. el. llVhen the plat-form l0 passes below the roller supports 39, as best shown in Fig. 5, there is a cessation in the movement of said platform and the hydraulic cylinders 4() are placed in operation, whereby the rollers 5l andI 53 can .move into engagement with the ed of the piece of paper and. fold the edges of the paper upon the article. 'the hydraulic cylinder hl() at the rear end of the machine is operated in advance `of the hydraulic cylinder at the forward end thereof, whereby the forward end of the' piece of paper will be folded ontoand scaled to the rear end of the piece of paper. Theroller 51 is operated in advance of therollers 53, and the rollers 53 close and seal the end flap upon the wrapper. The wrappingand sealing having been accomplished and the rollers 5l llO - position, asbest shown in Fi eject the article from the platform 10. The

platform 10 is then restoredto its normal 2, the shaft 24.y placed in operation and after the paper has been fed ytio the rearmost set of rolls 7, the shaft 24 is stopped and the operation as above described repeated.

' It is thought that the operation and .l lutility of thel machine will b eapparent without further description, and I would have it understood that the principles of my invention. can be embodied 1n a machine for wrapping various kinds of food stuffs and other material.
